Pinboard support

I recently purchased a pinboard account and I've come to love it dearly.

I'd love if you could perhaps include it as an option in the context menu or (preferably) a toggle to replace the "save to reddit" star option.

An example of this can be seen in the Google Reader app "Reeder", where in the options you can replace swipe to star with swipe to Instapaper or Read it Later (maybe another option in the toggle?)

Aside from that I absolutely adore your app!
